25% Oil Mix...Misprint?
I went to start my Redcat 30cc gas engine for the first time with a 4% oil mix in the tank and was shocked to see a sticker on the engine asking for 25% oil. Do they really want it that oily during break-in?

Actually, 4oz of oil per gallon is 32:1. For 25:1, you need to put 5.12oz of oil per gallon. I know that this is splitting hairs, but it might might help you engine to run cooler and last longer.

PS there are 128oz in a gallon

Its not an oily mix if you tune your engine right. My stock 26cc is almost 2 years old using Tanaka at 25-1 ratio. Use less oil and youll be buying a new motor.

do you guys have any issues withe the engine carboning up ( if thats a word) at 25:1. when i run my mixture at 25:1 my 26cc carbons up so bad it wont run any more but has been better since i changed my mixture to 45:1 using av gas and synthetic 2 stroke oil. it got so bad i had to take the motor apart and scrape the carbon off the piston and cylinder head.

The whole 25:1 mixture deal is for petroleum oils. Manufacturers recommend that ratio to cover their a s s !!! You can definitely use less oil once to go to high quality, 100% synthetics. I happen to run my mix at 40:1. Havent tried the av gas though. How do you like it compared to pump gas?

i noticed a good increase in power and seems to run a little cooler too. i also like the smell.

i should have mentioned i guess that my ratio is metric , milliliters to liters works out to be 22.5 ml oil to 1 liter gas i'm not sure what that is in ounces and gallons

Mine stated 35:1 (winter) / 32:1 and im kind of wondering if thats on the rich side. Albeit i cant recall if the 2cyl oil is a synth or not

Isnt AV gas like 100 octane? Higher octane fuel burns slower than lower octane fuel, I dont see how you can get a power increase from that, other than the lower oil content you are using... High octane is for higher compression ratios, so the fuel doesnt pre-ignite.

Oh, well the stroker or big bore are higher performance kits, and so they probaby would require the higher octane. My sttock 26cc wouldnt see a benefit. I use the 25-1 ratio with a quality oil Tanaka for example, and dont see any oil spewing out like a nitro, or carbonizing too much. I want the extra oil cushion on my needle bearing...
